I am tired already after getting up, feel like my body is swollen and have wind colic. Could this be liver problem? What should I do?

Diet. It sounds as though you are succumbing to chronic fatigue syndrome that, in my experience is due to high calorie malnutrition, too many empty calories, particularly sugar, ice cream, pop etc also caffeine can do this. Sharpen up on your diet and what you do when watchng tv etc.
